    Franklin-Spider Antenna (for advanced users)

    SIMULATION RESULTS Gain = 3.7 dBi SWR = 3.1 Impedance = 155 - j 8.18 ohms HIGH IMPEDANCE/SWR - WILL NOT GIVE GOOD RESULTS WITHOUT IMPEDANCE MATCHING IMPEDANCE MATCHING BY "TRANSMISSION LINE+CAPACITOR" TECHNIQUE Using Smith Chart: Capacitor to be inserted = 3.8 pF (4 pF will do) Coax length...
